- Specification of Letters Patent.

Application filed December 29, 1919. Serial No. 347,950.

To all whom it may concern:

Be it known that I, ELBERT A. M'oSPAD- DEN, a citizen of the UnitedStates, residing at Crawfordsville, in the county of Montgomery andState of Indiana, have invented a new and useful Damper Seat, of whichthe following is a specification.

This invention relates to a combined damper and flue cleaner, theprimary object of the invention being to provide a construction whereinthe damper may be operated to remove soot from the flue in which thepipe supporting the damper, is; supported.

Another object ofthe invention is to provide a pipe section especiallyconstructed to permit the same to be forced into a flue.

WVith the foregoing and other objects in moved back and forthlongitudinally to view, which will appear as the description proceeds,the invention resides in the combination and arrangement of parts and inthe details of construction hereinafter described and claimed, it beingunderstood that changes in the'precise embodiment of the inventionherein disclosed can be made within the scope of what is claimed withoutdeparting from the spirit of the invention.

A practicalembodiment of the invention is shown in the accompanyingdrawing, wherein Figure 1 is a sectional view through a flue andchimney, disclosing a damper seat and damper supported in the damperseat.

Figure 2 is an enlarged view in perspective of the damper seat;

Figure 3 is an enlarged fragmentary view in perspective of the damper. I

Referring to the drawing by numerals of reference 1 p A chimney isindicated at 1, and is provided with a flue 1, to which the usualopening 1 leads.

Within the opening 1",, and resting in the bottom of the flue 1, isplaced the clamper rest or seat, which consists of a short cylindricalportion 2 adapted to fit within the opening 1', and the integral,semi-cylindrical portion 3 which rests in the bottom if more than onestove has, communication with a single flue, the portion 3 should beprovided with an opening in the bottom' thereof to permit the productsof combustion to pass therethrough.

The end of a section of stove pipe 4 telescopes into the portion 2 ofthe damper seat, and an elbow 5 is provided at the other end of thesection of pipe 4:. The elbow 5'is formed with an aperture 6 throughwhich arod .7 is slidable, the rod extending longitudinally of thesection of pipe 4 and havr orrlca.

Patented Feb. 21, 1922. I

ing its outwardlyprojecting end bent to form an operating handle 8.

To the inner end of the rod 7, is secured the damper which consists of adisk 9, preferably having a slight port-ion cut away, as.

at 9, and apertured centrally toreceive the end of the rod 7, on whichit is bound by a nut 10, which nut of the rod. I

As will be understood, the rod 7 .may be is threaded on the end changethe position of the dafnper 9, and so vary the draft of-the chimney.When the damper is drawn tov the position shown in dotted lines inFigure 1, soot is scraped from the bottom of the flue and from the pipesection 4, and expelled through the elbow 5, thus keeping the entranceto the flue clean and assuring a proper draft.

Having thus described the invention, what is claimed as new and soughtby Letters Patent, is i In combination with a chimney having a flue andan opening in the flue, a damper seat consisting of a relatively shortpipe section having its outer extremlty formed as a semicylindricalportion, said damper seat adaptedto be positioned within the opening ofa flue, the outer extremity of the damper] ELBERT A.
